The Caterpillars of this species are black with white bands and a red thorax. The true legs are red and the prolegs are yellow. They feed on various plants from the family EUPHORBIACEAE :

  • Whitewood ( Endospermum medullosum ),
  • Toywood ( Endospermum myrmecophilum ),
  • Day Moth Vine ( Omphalea queenslandiae ), and
  • Omphalea papuana.

    These plants contain poisons which appear to protect the Caterpillars from predation, as in other Uraniids.

    To pupate, the Caterpillars lower themselves to the ground on a silk thread, and pupate in a cocoon in a crevice or between dead leaves.

    The adult moths are black with iridescent bands of yellow and pink. The underside is an iridescent pale green with black bands. The moths have a wingspan of about 10 cms. They fly by day, and feed on the nectar of various flowers. They rest with their wings open and out flat.

    They occur in the tropical north of Australia, in Queensland. In January in bright sunlight in the morning hours, the adult moths are common as singles and as mating pairs in light rainforest on both gentle and steep hillsides, in the area west of Cairns. They flutter fairly slowly and range from ground level to the treetops. They may be seen both laying eggs and resting.
